Problems solved by technology

On the other hand, because there is a lot of dust in the farmland, it is easy to accumulate dust on the surface of the solar cell, which will affect the power generation efficiency and even damage the solar cell. Therefore, how to keep the surface of the solar cell clean is also a major problem for solar photovoltaic greenhouses
US Patent US5101493 "PORTABLEGREENHOUSE WORKING ON SOLAR SYSTEM" introduces a mobile solar greenhouse that uses solar cells to generate electricity. The solar panels are placed on the roof of the existing greenhouse, but the panels take up a lot of space and are difficult to implement. Regulation of the am

Description

technical field [0001] The invention relates to a solar photovoltaic greenhouse suitable for cultivating tomatoes, in particular to a power supply device using an amorphous silicon solar battery panel as a greenhouse material. Background technique [0002] Tomatoes are one of the vegetable crops commonly planted in my country. At present, most of the tomatoes are grown in ordinary glass greenhouses or multi-span plastic greenhouses. The best solar irradiance intensity for tomato growing in greenhouse is 710μmol·m -2 ·s -1 ~1050μmol·m -2 ·s -1 In between, since the light transmittance of ordinary greenhouses to natural light is approximately a constant value (the light transmittance of glass greenhouses is 60% to 70%, and the light transmittance of multi-span plastic greenhouses is 50% to 60%). The light intensity adjustment range in the greenhouse is small, so it is difficult for ordinary greenhouses to adjust the amount of solar radiation injected into the greenhouse to...
